What cable management products does Qiongkai manufacture?

Qiongkai manufactures wire mesh (basket) cable trays, perforated and solid-bottom cable trays, ladder trays, heavy-duty series trays, cable trunking, conduit, tray accessories, strut channel in 41x21, 41x41, 41x62 and 41x82 profiles, seismic brackets and light-gauge metal stud framing.

Which finish should I choose: pre-galvanized, hot-dip galvanized, stainless steel or FRP?

Pre-galvanized and electro-galvanized steel suit dry indoor areas. Hot-dip galvanized steel is the common choice for outdoor and industrial plants. Stainless steel 304 suits food and clean environments, while 316/316L and FRP are preferred for coastal, offshore and chemical exposure. Our engineers can review your site conditions before you finalize the specification.

Can Qiongkai produce custom sizes and non-standard profiles?

Yes. With 12 assembly lines and about 60 heavy-duty machines across 3 factories, we produce custom widths, side heights, thicknesses, hole patterns and profiled sections, including a custom profiled section solution for an offshore LNG project in Qatar.

Which projects and markets has Qiongkai supplied?

References include corrosion-resistant CT series cable trunking for Shanghai Hongqiao International Airport, FRP cable trays for extreme conditions in Qatar and Thailand, FRP-lined steel trays for an outdoor project in Thailand, a heavy-duty tray solution for a large pig farm in Paraguay and HDG cable tray shipments to Italy.

Heavy Duty Pre Galvanized PG Hot Dip Galvanized HDG Carbon Steel Cable Tray with Reinforced Ribs 300x100mm Wholesale Factory Supplier

Product Overview

Perforated cable trays are specifically suited for indoor installations. A primary characteristic of perforated cable trays is their outstanding heat dissipation capabilities, efficiently supporting operating environments with critical ventilation requirements. Heat dissipation, airflow, and load-bearing performance are essential criteria during the cable tray selection process.

Engineered with distinctive wavy reinforced ribs on the bottom and side plates, these trays ensure enhanced mechanical load capacity alongside distinct visual identification. Products typically utilize a standard pill-shaped slotting pattern on all sides. Utilizing precision laser cutting machinery, a comprehensive range of perforated configurations is manufactured. Fully customized perforation geometries, patterns, and arrangements are available upon request.

Key Features

Strong Corrosion Resistance Develops a dense oxide protection layer with self-repairing properties, resisting moisture, acidic agents, alkalis, and salts.

High Wear Resistance The zinc surface layer delivers balanced hardness and impact durability, resisting continuous friction and handling damage.

Aesthetic Quality Features a uniform, high-gloss silver-white surface finish designed to prevent fading, discoloration, and weathering.

Superior Processability Excellent ductility and mechanical stability guarantee that galvanized layers stay crack-free and securely bonded during fabrication.

Cost-Effective Lifecycle Efficient manufacturing along with extended operational longevity minimizes maintenance, replacement, and total installation costs.

Environmentally Responsible Manufactured with reduced process emissions and inert in daily use, releasing zero toxic elements to comply with green standards.

Common Parameters

Zinc Layer Thickness: Protection ratings correspond with coating thickness. Available standard options include 10μm, 20μm, 30μm, 40μm, 45μm, 50μm, 60μm, and 65μm. Thicknesses beyond 65μm are manufactured on a custom-order basis.

Widths: Standard modular widths include 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, and 800mm.

Height: Common height options include 50mm, 60mm, 100mm, and 150mm.

Thickness: Gauge configurations for the tray profile and optional cover plate depend on mechanical load requirements. For steel galvanized units: when tray width B < 300mm, body thickness is at least 1.2mm (cover plate ≥ 1.0mm); for 300mm ≤ B < 500mm, body thickness is at least 1.5mm (cover plate ≥ 1.2mm).

Length: Standard production lengths measure 2m, 3m, 4m, and 6m, with adaptable dimensions available upon project demand.

Application Scenarios

These trays are utilized across construction, power distribution, telecommunications, petrochemical, and metallurgical sectors for orderly indoor and outdoor routing. Typical deployment spaces include vertical electrical shafts, building corridors, basement raceways, assembly workshops, utility substations, and industrial distribution units.

Frequently Asked Questions

What are the benefits of reinforced ribs on perforated cable trays?

The specialized wavy reinforced ribs integrated into both bottom and side plates substantially increase structural rigidity, allowing higher load capacity across spans while contributing to a recognizable, functional profile.

Can the hole pattern and perforation design be customized?

Yes. Beyond the standard pill-shaped perforation layout, custom hole sizes, configurations, spacings, and geometries can be fabricated through our laser cutting and automated production machinery.

Which surface treatments are available for corrosion protection?

Depending on installation environments and environmental ratings, finishes include pre-galvanizing, hot-dip galvanizing (HDG) with zinc layer thicknesses ranging from 10μm to over 65μm, and electrostatic powder coating.

Are free samples provided prior to volume orders?

Yes, free product samples are provided to facilitate structural, dimensional, and finish assessments before volume placement. Standard Minimum Order Quantity (MOQ) begins at 50 units.

Which international standards and certifications are supported?

The cable tray series is fully compliant with ISO quality benchmarks and CE manufacturing regulations, providing reliable adherence to global industrial and commercial safety standards.
